TimeField native time format

Describe the bug
TimeField is not in native time format. The TimeField is shown in the table as follows '00:00:04+00'.I just want it to be '00:00:04'.
'use_tz': False, same problem persists.

To Reproduce

from tortoise import Model, fields

SUPPORT_TYPE = (
    (1, 'Payment'),
    (2, 'Free'),
    (3, 'Continuous'),
)

class User(Model):
    id = fields.IntField(pk=True)
    username = fields.CharField(max_length=20, unique=True)
    password = fields.CharField(max_length=128, null=True)
    first_name = fields.CharField(max_length=60, null=True)
    last_name = fields.CharField(max_length=60, null=True)
    email = fields.CharField(max_length=60, unique=True)
    image = fields.CharField(max_length=60, null=True)
    phone = fields.CharField(max_length=30, null=True)
    created_at = fields.DatetimeField(auto_now_add=True)
    updated_at = fields.DatetimeField(auto_now=True)

    def full_name(self) -> str:
        if self.first_name or self.last_name:
            return f"{self.first_name or ''} {self.last_name or ''}".strip()
        return self.username

class Customer(Model):
    id = fields.BigIntField(pk=True)
    code = fields.CharField(max_length=30, null=True)
    name = fields.CharField(max_length=200)
    image = fields.CharField(max_length=60, null=True)
    website = fields.CharField(max_length=120, null=True)
    description = fields.TextField(null=True)

    class Meta:
        ordering = ["name"]

    def __str__(self) -> str:
        return self.name

class Support(Model):
    id = fields.BigIntField(pk=True)
    customer = fields.ForeignKeyField('models.Customer', on_delete=fields.CASCADE)
    user = fields.ForeignKeyField('models.User', on_delete=fields.CASCADE)
    support_type = fields.SmallIntField(choices=SUPPORT_TYPE)
    created_date = fields.DateField(auto_now_add=True)
    created_time = fields.TimeField()
    duration = fields.TimeField()

    class Meta:
        table = 'support'

    def __str__(self) -> str:
        return self.customer.name

from models import User, Support
from sanic import Sanic, response
from tortoise.contrib.sanic import register_tortoise

app = Sanic("WebServer")


@app.get("/support_list")
@app.ext.template("support_list.html")
async def list_support(request):
    objects = await Support.all()
    return {"objects": objects}


register_tortoise(
    app,
    db_url="postgres://postgres:root@localhost:5432/myweb",
    modules={"models": ["models"]},
    generate_schemas=True
)

if __name__ == '__main__':
    app.run(host="0.0.0.0", port=8000, debug=True, auto_reload=True)

Expected behavior
I am using Sanic framework postgresql database with Tortoise-orm.

Additional context

No repository file or test is named. Reproduce the shown TimeField example with PostgreSQL and trace where its value is formatted for the table; done means the displayed value is 00:00:04 rather than 00:00:04+00, with regression coverage for the reported case.
